Approved Supplier Lists in Oracle is the term used to describe a list of items and commodities that have approved sources from a list of suppliers.
All procurement organisations maintain lists that associate the items and services they buy with the companies who supply them, either formally or informally. Data stored in a controlled, global repository containing relevant details about each ship-from/ship-to/item relationship, is known as an Approved Supplier List (ASL).
